Raised the age limit to what? 18? Yeah I didn't think so.
One-line zingers aside, the question of age limits in figure skating does have an interesting history. Sonia Henie won the Norwegian championship at age 9 and competed in the Olympics at age 10. Somewhere along the line they set 12 as the age limit. I don't know exactly why they chose 12, or if there was any controversy or dissenting opinion about the rule at the time.
Marina Cherkasova medalled in pairs at 1978 Europeans at age 12. (She was 138 cm. tall -- 4'6") She and her older and bigger partner set all kinds of records for spectacular twists and throws until she grew a a little bigger a few years later.).
It was in 1996 that the change was made to the current rule of 15 by July 1st. But skaters who were already in the pipeline as seniors were grandfathered in. That was how Tara Lipinski was allowed to compete in -- and win -- 1997 Worlds.
From 1996 to 2000 they also had the exception for medallists at Junior Worlds, which allowed Sarah Hughes to compete at senior worlds -- and medal -- at 14.
For a few years the 15 rule only applied to ISU championships, but 14-year-olds were allowed to compete in other senior events such at the Grand Prix. In the 2005-2006 season Mao Asada beat the entire eventual 2006 Olympic podium, Arakawa, Cohen and Slutskaya, on the Grand Prix, but could not go to the Olympics or Worlds that year (her birthday is in September).
The current discussion is nothing new -- certainly it is not aimed at one particular coach or another. It is a tension between, on the one hand, wanting to protect children from being thrust into the adult world prematurely, and on the other, the fact that very young girls apparently can skate better than older ladies, so why hold them back?
What I don't go along with is all the anger and righteous indignation: "If you don't support the 'protect children' view, then aha! you are a child abuser!" "If you don't want children to compete against adults, then aha!, just as i thought, you hate Eteri!"
